I don't have an update notice on my end. What version of the game do you have? You'll see it when you start up the game.
1.1
Supposedly the newest version.
I've been screwing with my save a lot, could this have somehow triggered it?
Also, I tried to set "mii" as a pokemon since it was an option in the editor, and that corrupted the data, so I edited it back, and that made the save work again.
(unrelated note: the unreleased attack "enemy capture ball" is the best goddamn attack ever)
(another unrelated note: people say that changing your rank in the game will not do anything, THEY ARE WRONG! if you have unlocked the clothes and stuff in the store, setting your level to 80 will unlock everything all at once that you can buy. also, if you're setting it to 80 from a low level, then be ready to be owned by the pokemons in the balloon areas, but that can be easily fixed by going to the castle and trying one of their battles. oh also, you can unlock higher level challenges in the castle this way too. your rank does change back after you've done anything involving fighting pokemons, so make sure to do that last)
(third and final unrelated note: when experimenting with the game,
UNDER NO CIRCUMSTANCES SHOULD YOU START A NEW GAME, AND THEN RIGHT AFTER THE FIRST CHALLENGE, BEFORE BUYING ANY BALLOONS, SHOULD YOU EVER GO AND CHANGE YOUR LEVEL TO 80 TO BUY ALL THE BALLOONS! It works, but then when I went to press "up" to cause me to scroll down instantly to the lucky balloon, the game completely crashed on me, I needed to fight some pokes in a regular starter balloon before I could scroll down to it)
